(2020-04-16) Bjarre789: IT IS THE BEST ADBLOCKER EVER. BLOCKS EVERYTHING FINE AND YOUTUBE ADS THOOSE ARE SO ANNNNOYING. i recommend this adblock

(2020-04-16) Ryan Mumby: Does the job well, only problem is it doesnt stop mid video ads on facebook. anyway you can make it do that?thanks

(2020-04-16) Ahriman13: Literally the best adblocker on the market. And the most important, it is open source and free. Keep it up guys, cheers.
btw It would be awesome if you could get it work on the new Safari versions anyhow.

(2020-04-16) Jade Morle: AdBlock is a grandchild of uBlock Origin. uBlock Origin is the original program that Adblock was built off of since it was a free open source code at first. But take heed, take notice that Adblock is often confused with AdGuard.
AdGuard is a program, not an extension of your browser, and it monitors and profits from sitting in the background as a separate program and eyeballs ALL the sites you visit, keeping a record and roster of each one, then sells that information to ad marketing groups.
That is why, if you notice, uBlock Origin and AdBlock sit on the side as merely an extension of your browser (posting an icon in the upper right hand corner of your browser window) and does not hijack a list of monitored internet sites you visit like AdGuard does. AdGaurd tries to fraudulently deceive you around the point by claiming they protect off line content too within various apps, but all that means in real life is that they do that to get a list of your total computer activity, not just your internet browsing activity. AdGaurd is not a malicious program, but do not be deceived, IT IS AN INVASIVE PROGRAM!
Also, if you get use to using uBlock Origin you will see that they have settings in their control icon where you can block a pages' media data and what-not else, but you can also turn that off and be free to use media players and such on specific sites. You just have to tell it what to do. uBlock is by far the best out there right now IMHO if you include privacy, trust, and genuineness in their agreement with users.

(2020-04-16) pow bam: Been using it for years now. None other needed.

(2020-04-15) Prince Kaizen Namwali: Best extension of all time. This is a gift from the gods. I will enjoy it while it lasts, until the internet becomes completely decentralized.

(2020-04-15) A New Awakening of The San Joaquin: This is the best blocker I've encountered by far.

(2020-04-15) chill the Meerkat: So far the best ad-blocking extension out there. The only one that can successfully block performance-heavy ads on our news portals. Also with quite extensive options including blocking individual elements manually.

(2020-04-15) Olivia La: I've been using this for a long time, however it seemed to suddenly stop working on Crunchyroll. I have no idea why it stopped working since it used to work before. Please fix this!

(2020-04-14) Ultimate3dition: I noticed that there was more update on Google Chrome at the moment it is at version 1.26.0 but in chrome web store it is 1.24.4 will there be an update soon or not?

(2020-04-14) David Dinard: super vraiment efficace

(2020-04-14) Filip Adamík: Best adblock whatsoever. Works seamlessly.

(2020-04-14) Guest User: Useful blocks ads on youtube

(2020-04-13) hzf hzf: 好用

(2020-04-13) Being Abbas: Always Using this since 2013 , its always working fine , never dissapointed me ...

(2020-06-05, v:1.27.10) HunterOfHalfLife: YouTube adsit doesnt block youtube ads anymore. there are 30 second long ads when i first open the page.

(2020-06-04, v:1.27.10) Edik Torek: More Options for YT blockingI would like to motivate some YT uploaders.
I would like that add block would block adds on YouTube selectively with some options:
uploader did not uploaded Full HD 1080p or 720p quality,
uploader did not made same language subtitles, or even did not allow automatic subtitles.
Those should be independent options.
Quality should not be checked on videos, that have: Lyrics in title,
or word lyrics in other languages:
Letra, Letras (spanish/portuguese)
versuri romanian
avec parole, avec paroles, mit Text, mit Worten, LiedText, SongText, z tekstem, ze słowami,
текст песни, со словами, с текстом,
מילים, बोल, كلمات الاغنية
These additional keywords, should be optional and with possibility to further addition, and deletion, and even acquiring them through google translation, from one language to another.
And Could you make lyrics video YT browsing mode, that make disappearance of any video from YT related video, or YT search result, if there are no subtitles, or there is no Lyrics (or foreign Lyrics Letras words) in the title thereof.

(2020-06-04, v:1.27.10) Mikael Andersson: Background tabIt seem that when I am loading a tab "in background" the "My Filters" are not applied? Then I have to reload the page when it gets active?

(2020-06-04, v:1.27.10) Brinke Guthrie: what setting do i click...............if I DON'T want UBO to run on a specific site?

(2020-05-30, v:1.26.0) Stefan Nieuwenhuijse: ads no blockedGood day.
I have been using your adblocker for some time.
What I also really liked is that I could watch TV on the internet on the website: nlziet.nl.
So advertisements that you normally see on TV, that blocked ublock origin very well so that you could watch the entire broadcast without those annoying commercials.
Only recently he no longer blocks broadcasts, so you now have to wait and those annoying advertisements see more.
They may have removed something in the broadcast, so that your ad blocker will no longer see advertisements.
It still works well on YouTube and other websites!
Hopefully you can make something for it so that it will be blocked again.
I would like to hear from you.
Sincerely,
Stefan Nieuwenhuijse

(2020-05-27, v:1.26.0) Lorraine Lindsay: uBlock won't block a particular siteWhy is uBlock incapable of blocking the pdfwondershare.com site? As soon as I installed it, that site was the first one I put in. I get ads from them nearly every single day, have to either sit there and eventually wait for the pop-up to go away on its own, or click on it and then close the tab that comes up. Why?????

(2020-05-27, v:1.26.0) Jin Tian: uBlock origin is incompatible with WECHAT web versionWhen the uBlock origin is on, I cannot receive any new message on the WECHAT web version. The issue is gone after I turn off the uBlock origin or add it into whitelist.
WECHAT web version is at https://wx.qq.com/
It's popular in China.
I hope this incompatible issue will be fixed, thank you very much.

(2020-05-25, v:1.26.0) Joni Kinnunen: uBlock Origin has started to block all internet accessHi. For a couple of days now Chrome browser has been totally unable to connect to any site. All other browsers and networking apps work fine. Problem seems to be uBlock Origin as disabling it removes the problem. Chrome version 83.0.4103.61 (Official Build) (64-bit). uBlock Origin version 1.26.0.

(2020-05-25, v:1.26.0) Kim Allison: No longer blocking ads on HuluIt used to work for me for a good month when I first got this extension, now the 200+ second ads show up :(

(2020-05-22, v:1.26.0) TheTixonNick: The plug-in doesn't work anymore.More than over a year the plug-in worked properly. Now when I watch YouTube videos the ads pop up every third video. I don't know what to do. Please help me.

(2020-05-22, v:1.26.0) DirŦyDeeds: Launching chrome gives an error.For the last 2 weeks, I started getting an error everytime I open chrome up. ERR_BLOCKED_BY_CLIENT. Then chrome eventually loads up. Everything else seems to be working with Ublock Origin.

(2020-05-21, v:1.26.0) Troll Princess: YouTube adsI use chrome. I started having an error when I would start a video on YouTube. It said it couldn't load the video which, by the length, appeared to be an ad. If I waited, the video I was waiting for came up without the ad. Then, I started seeing ads before YouTube videos. My settings are the same as my husband's as far as we can tell and he's not seeing the ads.

(2020-05-20, v:1.26.0) Rene G: gets corrupted on regular basison latests macos and chrome the extension keeps getting corrupted. I already tried to remove my profile and all other extensions. yet it just disables and gets corrupted without any error message or notice

(2020-05-17, v:1.26.0) Roberto Castanos: Blocking all websites.Hi! Great product. I've used it for years. Continues to work fine on Firefox, but it is blocking every website I go to on Chrome. I figured it out by disabling every single extension, then enabling one by one. This extension is the culprit.
